ALBERT V. PICKERING, 0F. WOONSOCKET, RHODE ISLAND OIL BURNER Application filed March 28, 1927. Serial No. 179,067.

The present invention relates to oil burners and has for its principal object to provide an improved structure having a combined natural and forced draft directed from below the burner upwardly thereabove and then downwardly directly on top of the burner.

Another important object of the invention lies in the provision of an oil burner of this nature that is exceedingly simple in its construction, inexpensive to manufacture, economical to operate, compact and convenient, thoroughly eflicient and reliable in operation, and otherwise well adapted to the purpose for which it is designed. I

With the above and numerous otherobjects in view as will appear as the description. proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

The figure is a side elevation of an oil burner embodying the features of my invention, portions being shown .in section.

Referring to the drawing in detail it will be seen that the numeral 5 denotes a blower and the numeral 6 denotes a horizontal conduit extending from the blower and having a sump 7 formed ina portion'of the bottom thereof and divided from the remaining portion by means of a partition 8 that is horizontally disposed and below the partition the sump is provided with a ii-shaped opening 9 for admitting the natural draft. The end of the conduit 6 is suitably attached to a coupling 10. An elbow 1.1 has its horizontal portion 12 attached to the coupling 10 while its vertical portion terminates in a channelled annular bead 13 for receiving a cylindrical section let the upper end of which terminates in an annular channelled bead 15. One or more of the cylindrical sections 14 may be used to increase the height of the burner in the heater or the original sections ll may be manufactured in 'difierent sizes for the same purpose. denotes generally'the burnerfcasing which is of acup-shaped formation having its bot- The letter C tom open and the edge thereof resting in the channel of the head 15. The burner C is substantially the same as that shown and described in my Patent No. 1,714,569, dated Mav 28, 1929. r

he important features of this invention reside in the utility of both a natural and a forced draft as is clearly illustrated in the drawing and in the adjustability of the burner because of section 14. The burneras a whole is supported upon a foot 32 and a foot 33.

It is thought that the construction, utility, operation and advantages of this invention will. now be quite apparent to those skilled in the art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description. It will be apparent that changes in the detailsof construction, and in the combination and. ar *angement of parts may be resorted to without departing from the spirit or scope of the inventlon as hereinafter claimed or sacrific- I ing; any of its advantages.

Having thus described my invention, what I claim as new is: r r

In a structure of the class described an elongated horizontally disposed tubular conduit having a depression in one end, a hori-' zontally disposed partition wall interior of the conduit and extending a portion of the length thereof above the depression, said partition wall dividing said one end of the conduit into pair of spaced axially extending passages, a blower operatively connected withv one of the passages, the walls of the conduit formed with an opening leading into the oth r of the passages, means connected with the other end of the conduit for conducting the air in a vertical column, and a burner casing supported on said means.

In testimony whereof I affix my signature.

ALBERT V. PICKERING.
